Drop the nightly random-seed test job

The job only ran on a schedule, so on every pull request it surfaced as a
skipped check that contributed nothing but a line of noise to the status
list. Ordering leaks are still caught: the fixed-seed randomized run stays
in the main check, where a failure blocks the merge that caused it instead
of being reported hours later against an unrelated commit.
